Formal Specification of λ*_V2 (ARBE λ*) – Version 1.0
Today I published a formal specification of λ*_V2, defining it as the unique energetic balance point of a measured reflectance spectrum over 380–730 nm.
The specification establishes:
• the governing integral equation
• deterministic root-finding (Brent method)
• strict methodological boundaries
• distinction from centroid-based metrics
• reproducibility requirements
The aim is not to introduce a new color space, but to provide a physically grounded ordering parameter derived directly from measured spectra.
Open, transparent, and reproducible definitions are essential for stable color workflows across research and industry.
